The Physical Resource Block collocation method of subscriber equipment and search volume thereof, system side

Technical field

The present invention relates to field of mobile wireless communication, particularly relate to Physical Resource Block collocation method, subscriber equipment and the system side in a kind of user equipment searches of wireless communication system space.

Background technology

Along with the development of Mobile Communication Industry, and continuous growth to mobile data services demand, speed and service quality (the Quality of service of people to mobile communication, Qos) requirement is more and more higher, so at 3G (Third Generation) Moblie (3rd Generation, 3G) before also there is no extensive commercialization, just start the research-and-development activity to next generation mobile communication system, wherein relatively be typically third generation partner program (3rd Generation Partnership Project, Long Term Evolution (LTE 3GPP) starting, Long Term Evolution, Long Term Evolution) project, the available maximum spectrum bandwidth of LTE system is 20MHz (megahertz).Along with the further evolution of network, LTE-A (evolution LTE), as the evolution system of LTE, can provide the spectral bandwidth up to 100MHz, supports more flexible higher-quality communication, and LTE-A system possesses good backwards compatibility simultaneously.In LTE-A system, have multiple component carriers (CC, component carrier), a LTE terminal can only be operated on the CC of some backward compatibility, and the stronger LTE-A terminal of ability can be transmitted simultaneously on multiple CC.Realize terminal transmission and the reception data in multiple component carriers simultaneously of LTE-A, thereby reach the object that promotes bandwidth.This technology is called as multi-carrier polymerizing technology.

In the research of present stage, on the basis of multi-carrier polymerizing technology, the LTE R11 stage is for frequency spectrum resource utilization rate, network energy-saving, and interference inhibition aspect between community has proposed new demand.In order to realize this purpose, new carrier wave (New Carrier Type is called for short NCT) is proposed at present.Apply by means of carrier aggregation technology, new carrier wave has a salient feature, does not need to consider backwards compatibility exactly in the time of design, can apply more new technology therein.For example, in LTE R11, be defined as for new carrier wave at present, need and at least one compatible carrier wave pairing operation (also referred to as carrying out the operation of carrier aggregation mode with a compatible carrier wave), in new carrier wave, do not configure cell reference signals (the Cell-specific Reference Signals of LTE R8, be called for short CRS), disturb at the serious CRS of cell edge to avoid adjacent cell, particularly under HetNet (HETerogeneous NETwork, heterogeneous network) scene, the CRS between macrocell and Microcell disturbs.

Further, because the progress of LTE R11 is slower, finally consider the standard operation that can not complete NCT in timing node, so just the correlative study of NCT technology is postponed till in LTE R12, the content of having agreed in LTER11 is still accepted.The standardization effort of LTE R12 does not also start at present, there is more company to think, in LTE R12, not only to continue to study the NCT of LTE R11, also need further to increase other NCT technology, for example propose independent operation NCT (standalone NCT), there is independent operation ability.In order to be different from the NCT in LTE R11, because the NCT in LTE R11 need to configure a backward compatibility carrier wave, so be called as dependent operation NCT (non-standalone NCT), NCT is owing to wherein having deleted local channel/signaling, so need to be by runing with the compatible carrier wave of its pairing in dependent operation.

Further, in independent operation NCT, determine ePDCCH (enhanced Physical Downlink Control Channel, strengthen Physical Downlink Control Channel) USS (UE specific Search Space, user equipment specific search volume) PRB (the Physical Resource Block that takies, Physical Resource Block) right position notifies by high-level signaling, concrete, to adopt UE (User Equipment, subscriber equipment) dedicated mode to carry out.Can make like this PRB of the USS of UE configure the PRB couple of public USS to accomplishing the UE for partly needing, for example, at COMP (Coordinated Multi-Point, coordinate multipoint) in for need cooperation UE, respectively by their USS of signal deployment at identical PRB to interior, be conducive to UE and reduce search volume, also can not affect the PRB configuration of the USS of other irrelevant UE.

For adopting UE dedicated radio resources control (Radio Resource Control, be called for short RRC) the right position of PRB of USS of the ePDCCH of message informing UE, there is at present problem below: UE from descending access until set up the process of RRC connection, must need in random access procedure, wherein need to receive the msg4 (Message4 of one of downstream message in random access procedure, message 4), if msg4 adopts DCI (the Downlink Control Information that sends scheduling in the USS of UE so, Downlink Control Information), how about does UE know the right position of PRB at the USS place of oneself so? another problem is: suppose that UE has completed random access procedure by other means, so, base station need to send some special RRC message for UE, when now UE receives the Article 1 special RRC message of base station transmission, special RRC message is dispatched transmission by USS, is the USS that how about UE knows this Article 1 special RRC message of scheduling so which PRB centering?

Obviously, according to current conclusion, the PRB of the USS of UE is to being to send to UE's by the special RRC message of UE, first the transmission of special RRC message needs to set up RRC connection so, at present, just need PRB that UE knows USS to position setting up process that RRC connects, or the PRB that just need to know USS in the time that UE receives Article 1 special RRC message is to position.

The embodiment of the present invention also provides the Physical Resource Block collocation method in a kind of user equipment searches space, comprising:

Subscriber equipment obtains the right position of Physical Resource Block PRB of acquiescence USS according to the notice of system side, or, the right position of PRB of the described acquiescence of described subscriber equipment and described system side agreement USS, the PRB of described acquiescence USS to for described subscriber equipment at the PRB of USS that does not receive the described subscriber equipment that described system side configures by dedicated radio resources control message PRB couple as the USS of described subscriber equipment during to position.

User equipment side is corresponding with system side, and multiple details of describing in the method for system side are equally applicable to user equipment side, have therefore omitted being repeated in this description same or similar part.

System side arranges the PRB couple of acquiescence USS, and by the PRB of acquiescence USS to position informing to UE, or system side in advance with acquisition pattern or the position of UE agreement acquiescence USS, UE gives tacit consent to the PRB couple of USS according to acquisition pattern or location positioning.

System side adopts system broadcast message to notify the right position of PRB of acquiescence USS, wherein preferably carries with the MIB in system broadcast message or SIBs.For SIBs, be preferably SIB1, SIB2.Also can use for other SIBs, but preferably before random access is carried out UE must to receive SIB be main.When UE receives after the system broadcast message of the position that the PRB of the carrying acquiescence USS that system side sends is right, UE just can be known the right position of PRB of acquiescence USS, thereby make UE in follow-up operation, while not receiving the right position of the PRB of USS that system side sends, can use the PRB couple of acquiescence USS, system side too, the PRB of USS that does not send configuration UE for UE when system side is during to the signaling of position, the PRB of system side by the acquiescence USS of UE is to sending the schedule information of UE, schedule information comprises DCI information, ePHICH (Enhanced Physical hybrid-ARQ indicator channel, the physical mixed ARQ indicating channel strengthening).

The PRB centering of the eCSS that system side can also adopt at ePDCCH sends DCI, by the right position of PRB of the information indication acquiescence USS in the DCI sending.UE receives after the DCI information of PRB centering transmission of the eCSS of ePDCCH, resolve DCI information, from DCI information, find whether to have the PRB of acquiescence USS to position, if had, UE do not know system side be oneself configuration USS PRB to time, can use the PRB couple of this acquiescence USS.Described DCI adopts the public RNTI (Radio Network Temporary Identifier, Radio Network Temporary Identifier) of agreement to carry out scrambling.

If the PRB of acquiescence USS to the PRB of USS to exist simultaneously, the PRB of system side and UE side agreement USS is to preferentially being used.Or the PRB of agreement acquiescence USS is to preferentially being used.Or system side is indicated UE by signaling, the PRB of acquiescence USS to or the PRB of USS to being used, can make like this UE only to retrieving, can reduce the range of search of UE to a certain PRB wherein.

The mode of the PRB that system side and UE side adopt agreement acquiescence USS in advance to position and number, directly like this solidifies by standardized way, has saved the expense of signaling.System side sends the schedule information of UE to position and number according to the PRB of the acquiescence USS of agreement, UE side also goes to receive the schedule information of oneself to position according to the PRB of the acquiescence USS of agreement.Determine the mode of PRB to position of acquiescence USS for prior agreement, preferred, PRB is to being positioned in the middle of system bandwidth right one or more of 6 PRB, wherein preferred, in the middle of being fixed as, 6 PRB centering number order are front several, and concrete quantity obtains according to emulation, for example first 1 or first 2.

There is corresponding relation to position and one or more definite channel/signal in the PRB that system side and UE also can arrange to give tacit consent to USS, system side and UE all can be according to the PRB of the unique definite acquiescence USS of described corresponding relation to positions.

System side and UE side agreement are utilized community physical I D to calculate and are obtained the PRB that gives tacit consent to USS to position, for example, utilize community physical I D value to 6 complementations, remainder value or remainder value add the PRB of the corresponding acquiescence of 1 rear institute value USS to 6 positions that PRB is right in the middle of system bandwidth.Base station side utilizes community physical I D to calculate in the manner described above the right position of PRB of acquiescence USS, then sends the information of dispatching UE this PRB centering, as DCI.Behind UE access community, obtain community physical I D, then calculate in the manner described above the right position of PRB of acquiescence USS, then do not obtain base station be the PRB of USS of own configuration right in, retrieve oneself schedule information the PRB centering of this acquiescence USS.

Certainly the PRB of acquiescence USS is to being placed on any PRB centering of system bandwidth, 6 PRB centerings in the middle of above-mentioned being placed on, mainly because be conducive to support like this machine type communication (MTC, Machine-Type Communication) UE, for example a kind of MTC UE that does not possess the large bandwidth of access wishes to be operated in large bandwidth system, 6 PRB centerings in the middle of now just the acquiescence USS of system can being configured in, like this, this class UE just can access smoothly and work.

Can also utilize community physical I D for the right number complementation of the maximum PRB in this community, remainder value or remainder add the PRB position right to the PRB in system bandwidth of the corresponding acquiescence of 1 rear institute value USS, so just can make to give tacit consent to USS and be arranged in arbitrary PRB centering of whole bandwidth.

System side can by the PRB of acquiescence USS to position configuration be odd number or even number along with frame number time position difference, and in all odd numbers or even frame, the PRB of acquiescence USS is identical to position.The PRB that UE determines acquiescence USS according to the rule of agreement in odd number or even frame is to position.In other words, we can be for the PRB of acquiescence USS be to place subframe or frame position configuration cycle, and the PRB of acquiescence USS to only configuring in the subframe definite according to the cycle or frame.The size in cycle is by signaling UE, and signaling is carried by MIB or SIBs or cycle size is fixed; The original position of subframe or frame also can be passed through signaling, and signaling is carried by MIB or SIBs or original position is fixed.

In the subframe of cycle arrival, the right position of PRB of allocating default USS is fixed, and number is identical; Or, in described subframe, give tacit consent to the PRB of USS to position difference, but number is identical; Or the PRB that gives tacit consent to USS in described subframe is identical to original position, but number difference.

System side the PRB of allocating default USS to time, the PRB of the acquiescence USS of neighbor cell is orthogonal to position, or the PRB of the acquiescence USS of neighbor cell is when to position, all identical or part is identical, and neighbor cell is orthogonal to the CCE of interior use at the PRB of acquiescence USS.

System side can be by sending special RRC message indication acquiescence USS for UE PRB to being the PRB couple of USS of UE, be used to the control information of UE transmission schedule data transmission, for example dispatch the DCI of PDSCH.UE the PRB that obtains the special RRC message indication acquiescence USS that system side sends to be USS PRB to time, UE is in the PRB of USS centering receiving scheduling information.

System side and UE approximately fix on the DCI of the msg4 in the PRB centering transmission dispatching uplink random access procedure of giving tacit consent to USS.For example, when base station need to send when msg4 for UE, base station just sends schedule information DCI that msg4 is corresponding to UE the PRB centering of acquiescence USS, and in the time that UE need to receive msg4, UE retrieves the schedule information DCI of msg4 the PRB centering of acquiescence USS.

System side and UE approximately fix on the DCI of PRB to schedule information of acquiescence USS, and this DCI is used for scheduling and sends first the RRC specific messages of UE.For example, in the time need to sending first RRC specific messages after RRC connection is set up for UE, base station sends the DCI of first RRC specific messages the PRB centering of acquiescence USS, when UE accepts first RRC specific messages after RRC connects foundation, UE retrieves corresponding DCI the PRB centering of acquiescence USS.

System side also can be arranged with UE, and the PRB of acquiescence USS is identical to position with the PRB of eCSS to position, and both are identical PRB centering, and standardization is curing.

System side indicates the PRB of acquiescence USS during to position by signaling, the PRB that system side can be given tacit consent to USS by signal deployment to position with the PRB of eCSS to identical, or part is identical.

When the PRB of acquiescence USS to the PRB of position and eCSS when identical, system side is different from the CCE scope of eCSS use with the CCE that UE agreement acquiescence USS uses, and scope is fixed.Or the CCE that system side and UE side agreement acquiescence USS use comprises that described PRB is to interior all CCE, eCSS can only use the CCE into eCSS agreement.

System side and UE side are arranged in advance, acquiescence USS PRB be there is to agreement relation to position in the PRB of position and eCSS: acquiescence USS PRB to according to number be close to eCSS backward or forward PRB to position.Concrete, according to numbering backward or forward time, if the PRB of reference numeral is not when depositing, according to numbering next-door neighbour principle circulate determine acquiescence USS PRB to position.

For example, in system bandwidth, have 6 PRB couple, be numbered 0～5, if the PRB of eCSS is to being numbered 4 (suppose eCSS only use a PRB to), so according to numbering next-door neighbour's principle backward, give tacit consent to so the PRB of USS right be numbered 5 (assumed by default USS use a PRB to), and for example, if the PRB of eCSS is to being numbered 5 (suppose eCSS only use a PRB to), so according to numbering next-door neighbour backward, and the principle of circulation, give tacit consent to so the PRB of USS right be numbered 0 (assumed by default USS use a PRB to).Being close to forward for PRB numbering is similar processing.

UE side is obtained the PRB of acquiescence USS of setting to rear, and when UE is not in the time there is no to obtain PRB for the USS of own configuration to position, UE is in the schedule information of the PRB centering reception oneself of acquiescence USS, as DCI.

UE can be according to the PRB of acquiescence USS of agreement to position, or the PRB of the allocating default USS that sends by receiving system side of UE determines that to the signaling of position the PRB that gives tacit consent to USS is to position, and receiving system side sends the DCI of oneself therein.Wherein, the PRB couple of the USS of the PRB of acquiescence USS to the UE using before the PRB of USS of UE that does not receive special RRC message configuration is to position for UE.

When concrete enforcement when the PRB centering of acquiescence USS has PSS/SSS (Primary Synchronization Signal/Secondary Synchronization Signal, primary/secondary synchronizing signal), PBCH (Physical Broadcast CHannel, Physical Broadcast Channel), ePBCH (Enhanced Physical Broadcast CHannel, the Physical Broadcast Channel strengthening), DMRS (Demodulation Reference Signal, demodulated reference signal), CSI-RS (Channel State Information Reference Signal, channel state information reference signals) or when CRS, in the Resource Unit that acquiescence USS uses, remove PSS/SSS, PBCH, ePBCH or DMRS, CSI-RS, the Resource Unit that CRS takies.In the Resource Unit that UE takies while not also being desirably in above-mentioned PSS/SSS, PBCH, ePBCH, DMRS, CSI-RS or CRS, receive the data of USS.Or when the PRB of acquiescence USS is when comprising CSI-RS, in the Resource Unit of CSI-RS place, do not send CSI-RS, this Resource Unit is as sending acquiescence USS, and UE receives acquiescence USS in this Resource Unit, and does not expect to receive CSI-RS.

System side comprises base station, relay station, RRH (Remote Radio Head, remote radio head).

All can complete the right position indication of PRB of acquiescence USS for such scheme, if further want the PRB couple of the USS that indicates ePDCCH set, also can use aforesaid way completely, only need the PRB of acquiescence USS replacing with the PRB couple of USS of ePDCCH set.

The following describes at the PRB of acquiescence USS that has obtained ePDCCH rear, how concrete uses these PRB to the mapping (mapping of the actual USS of being or eCSS) for ePDCCH.Use K to represent the total number of the set that the PRB of ePDCCH is right or represent the total number of ePDCCH set, set be in advance using several PRB to as a set, will gather and indicate to UE, UE retrieves USS or the CSS of ePDCCH in the PRB of set-inclusion.For example, 2 of set-inclusions or 4 or 8 PRB couple, the PRB of set-inclusion represents with N number.PRB in a set, to being discrete, can be also continuous, represents number and the continuous PRB number to the set that form of discrete PRB to the set forming, K >=KL+KD respectively with KL and KD.For example, while stipulating K=2, KL and KD can combine according to mode below:

{KL＝1，KD＝0}，{KL＝0，KD＝1}，{KL＝1，KD＝1}，{KL＝0，KD＝2}，{KL＝2，KD＝0}。

The value of N is { 2,4,8}.

Further regulation, for the USS of the ePDCCH of independent operation NCT, except using above-mentioned mode, also comprises below:

KL and KD adopt default configuration or adopt signaling is UE indication.If employing default configuration, for example: the configuration of regulation KL and KD is only the one in above-mentioned combination and combination below, K=3, KL and KD are combined as { KL=0, KD=1}, { KL=1, KD=0}, { KL=0, KD=2}, { KL=2, KD=0}, { KL=1, KD=1}, { KL=0, KD=3}, { KL=1, KD=2}, { KL=2, KD=1}, { KL=3, KD=0}.

If adopting signaling is UE indication, signaling is that UE sends by broadcast system information or special RRC message so, and concrete set K, KL, KD or N value can be given the UE needing by this signaling.

The USS of ePDCCH in independent operation NCT, for above-mentioned N value, can adopt 2 or 4.Or according to system bandwidth definition acquiescence N value, the N value that different system bandwidth is corresponding different.For example, the relation shown in following table 1.

Table 1

Also can adopt the predefine mode of table 2.

Table 2

Further, for independent operation NCT, indicating the acquiescence PRB of ePDCCH to rear, also existing and need to indicate ePDCCH specifically to shine upon from that OFDM sign-on of PRB centering, namely initial OFDM symbol.Here for the different acquiescence OFDM symbol original position of dissimilar subframe definition, or be fixed as the 3rd or 4 OFDM be primary sign, further the initial OFDM symbol of the PDSCH of ePDCCH scheduling is identical with the initial OFDM symbol of ePDCCH.For example, when MBSFN subframe corresponding to PMCH, the initial OFDM symbol of acquiescence ePDCCH is the 3rd OFDM symbol; The initial OFDM symbol of acquiescence ePDCCH corresponding to conventional subframe is the 4th OFDM symbol.

Further, for NCT carrier wave, DMRS scramble sequence initial parameter X is the C-RNTI of community cell ID or UE or the interim C-RNTI of UE.The position of ePDCCH corresponding initial eCCE in described PRB set is determined according to HASH (Hash) function.

When the ePDCCH of descending carrier sends descending scheduling, the initial position of the PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) in its corresponding up-link carrier configures in SIB.Further, before not receiving the relevant USS configuration of relevant ePDCCH RRC message, UE uses the PUCCH initial position of acquiescence, for example, use the position of the PUCCH that ePDCCH is corresponding (1), or, in ePBCH or SIB, configure its initial position.Concrete, in the time that UE does not receive the configuration information of the configuration information of ePDCCH set or the acquiescence USS of ePDCCH, UE uses the position of the PUCCH (1) that ePDCCH is corresponding, or UE uses the position of the PUCCH receiving from ePBCH or SIB.

The embodiment of the present invention also provides a kind of system side, as shown in Figure 1, comprising:
